Product Description
The Cheminert ® M Series liquid handling pump is a syringe-free pump
capable of delivering a bidirectional flow to six orders of magnitude. It
is a positive displacement pump, which means that it is self-priming and
tolerant of any gas which may find its way into the fluid lines. Since there
is no separate fill cycle, the pump can be operated continuously, and
volumetric capacity is limited only by time.
RS-232 and RS-485 communication protocols are incorporated into the
microprocessor-driven controller. (USB interface requires an adapter.)
The M Series pump is recommended for any liquid handling applications re-
quiring accuracy and precision. It is particularly suited for applications with
a wide range of volumes (which entail laborious syringe changes with other
pumps) and for applications which benefit from the versatility provided when
the pump is coupled with the optional multiposition reagent selection valve.
Operating Principle
At the core of the pump is a rotor which houses four pistons. As the micro-
stepper motor turns the rotor, the pistons float on a stationary cam; at any
given moment, one piston is filling, one is dispensing, and the other two are
in transit between the fill and dispense positions.
Software
The pump comes complete with M6-LHS software, which employs standard
liquid handling terminology and an integrated valve control package in a
familiar Windows format for everyday lab usage. For more advanced control
of system parameters, IMS (Intelligent Motion Systems) software can be
downloaded directly from the IMS website at www.imshome.com. Hardware
installation (pages 4-5) is the same for all users.
